Which of the following is NOT a function of the skin?Nutrient Absorption from foodProduction of vitaminsRegulation of body temperatureBarrier protection

To determine which option is NOT a function of the skin, let's analyze the roles of the skin based on the given choices:

1. Nutrient Absorption from food: Skin does not absorb nutrients from food. Nutrient absorption primarily occurs in the digestive system. While some substances can penetrate the skin (like certain medications), this is not a primary function.

2. Production of vitamins: The skin is involved in the production of Vitamin D when exposed to sunlight, which is an essential function.

3. Regulation of body temperature: The skin plays a critical role in thermoregulation through processes like sweating and changing blood flow.

4. Barrier protection: The skin serves as a barrier against environmental damage, pathogens, and physical injuries.

Conclusion:

The correct answer is Nutrient Absorption from food, as it is not a primary function of the skin.
